Виявлення керуючих сигналів при керуванні безпілотними літальними системами

Abstract

This paper addresses the issue of detecting control signals in unmanned aerial vehicle (UAV) communication systems operating under the 802.11 standard. The standard method for determining the start of a data packet relies on computing the correlation of the received signal with a reference sequence to form a plateau. While effective in standard conditions, this plateau-based approach fails under heavy noise or electronic warfare (EW) interference, causing the correlation plateau to become uneven or fragmented. To solve this problem, the authors propose an alternative method based on detecting individual correlation peaks.
